Answer:
(-4,-9)
Step-by-step explanation:
Given a segment AB with endpoints with coordinates
A:
B:
The coordinates of the midpoint M of the segment AB are given by:
(1)
In this problem, we know that:
- The midpoint of the segment AB has coordinates
- One of the endpoint of the segment has coordinates
So we can find the coordinates of the other endpoint A by re-arranging eq.(1) above:
And substituting, we find:
So, the coordinates of the other endpoint are (-4,-9).
Answer:
The answer is B and C.
Step-by-step explanation:
Ok so i need the answer also
3*3+2y=20
9+2y=20
2y=11
Y=11/2
Answer:
It is not a right triangle.
Step-by-step explanation:
We can prove this by Pythagorean theorem because it represents to a right triangle.
Pythagorean theorem:
a² + b² = c²
Now substitute the values.
Note: the longest side will represent c
So,
a = 10 m
b = 16 m
c = 20 m
10² + 16² = 20²
The objective here is to make them equal.
100 + 256 = 400
356 ≠ 400
They are not equal so it is not considered a right triangle.
